Screening is advised since undernutrition is linked to worse clinical outcomes. It is crucial that this topic be researched due to the lack of knowledge on nutritional status and the clinical effects of undernutrition in hospitalized Pulmonology patients. Undernutrition was assessed using the Malnutrition Universal Screening Tool as part of a longitudinal study of patients who had been consecutively admitted to a pulmonology hospital department. The risk of undernutrition was quantified as a function of length of hospital stay, pathology type, and discharge location. It was discovered that a significant number of patients were at high and moderate risk for undernutrition. Hospital deaths were more likely to occur in patients who were at risk of undernutrition. outcome in therapeutic trials, it should be regularly assessed using validated questionnaires. The danger of undernutrition affects one out of every three patients admitted to this unit, with chronic obstructive pulmonary disease being the pathology most strongly linked to the risk. A screening for undernutrition should be done upon admission, according to the most recent statistics.
